Description leo 2017-06-29 14:04:32 UTC
Description:
Hi,
my company is using impress to present our services to clients. In one of our presentations, we have a pretty heavy slide, with various items that appear one by one.
The problem is that when we edit the .odp, everything appears good, same when we export it as a .pdf file. But when we view it on full screen, using impress, the image is having some appearance bugs (unwanted lines or shapes appear on the slide). 
Also, this happens in every computer we've tried it on.

Steps to Reproduce:
1. open .odp file
2. go to this particular slide
3. activate fullscreen mode

Actual Results:  
the screen has unwanted line and shapes

Expected Results:
have the slide appear as it does when we watch it in editing mode or as a .pdf file.


Reproducible: Always

User Profile Reset: No

If the document contains information you do not want public, please somehow try to figure out a way to create a minimal reproducer case and attach to this report. If it is larger than 10MB, then use a file hosting service like http://wikisend.com/

Set to NEEDINFO.
Change back to UNCONFIRMED after you have provided the document.

So, i isolated the slide I was talking about, you need to preview it on fullscreen and you'll see what i'm talking about (the lines and stuff appearing).

Ok, I confirm.

it's only impress objects

So i asked the creator of this presentation, he says it's only impress objects, nothing else.
I attached an enlightened version of the same slide, that still shows the same bug.
Thanks a lot for answering so quickly !

So, is there anything we can do?

Since this is Linux-only now, probably not related to Windows Bug 40534 that is related to large screen/high resolution. 
But please anyway note resolution and try with some smaller resolution. 
Please try with hardware acceleration disabled.

We need to find out when and why it started, is this some recent error or it was always like this, since OpenOffice.

In Linux you may use Bash Script from http://pastebin.com/L6SFSYFR (just run /bin/LO-extract.sh) to Extract Parallel LO (no installation) from downloaded and unzipped LO folder with DEBS. 
Then you may test newer LO 5.2, 5.3, 5.4 and master 6.0+. But you may also test older versions to find earliest version affected.
Please note different Bug 107090 from LO 5.3.

I confirm the bug! but with really different effects.
I uploaded two screenshots for ease: https://imgur.com/a/Vr1JahR

in the first, it shows what I see just opening the .odp file
in the second, it shows the (F5) full-screen appearance and as you can see it misses much elements.
